We also had some resistance but it hasn’t gotten to the point where we felt the need to reconsider. It took a few days of adjusting as some internal email was being flagged incorrectly and there was objection to flagging student messages and some hosted web applications. All in all there was also positive feedback and the campus seems to have adjusted well to it. Interesting approach, but doesn't this break DKIM signatures? -- Alan Amesbury University Information Security http://umn.edu/lookup/amesbury
